RE: [Elecraft] K2 Speaker Replacement
Makes sense to me!

By accident at field day I overloaded the K2's speaker with too strong a signal and with the volume accidentally turned up and I think I blew it out. It sounds like crap now.. yet plugging in an external speaker sounds just fine. Should I contact Elecraft for a replacement or is there some speaker that is a 'must have' to replace the internal one?

Re: [Elecraft] K2 Speaker Replacement
James, Before replacing, it may be that you only knocked it off center of the voice coil. Take out the speaker and view it from all angles. Is the Cone off center? If the thing looks like it is, you might put three fingers and thumb equally around edge of voice coil at narrow end of cone, and push in gently and release. This might restore the centering. If not, you have not lost much time. There is also the possibility that you had such as strong signal that you magnetized part of the frame of the speaker. That is more tricky, but you might use a compass to see if symmetrical positions around the speaker frame circumference the compass needle deflects the same amount. You do this by putting speaker in a circle you have drawn on paper by tracing around the magnet. Now, carefully tie a string onto compass so that you may keep it a defined distance from the framework as you move it to differing positions. Keep string taut between frame and compass for each datapoint. You could record the amplitudes as so many degrees from North, 0 degrees. If you find a very unsymmetrical magnetic field plot, you might as well order a replacement speaker from Elecraft. You might be able to degauss the frame with a VCR tape hand held degausser of the Hockey Puck style that Hi Fi shops used to sell, but you do not want to degauss the permanent magnet at the back of the cone.
